Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Referring to figs. 1 to shown in Fig. 3, a kind of center current divider of spin stabilization, including oil path block 1, rotary core 2, bearing 3.
Oil path block 1 is equipped with installation position 11, and installation position 11 includes the through hole 12 for running through oil path block 1, is respectively arranged on and runs through
Two bearing grooves 13 at 12 both ends of hole there are two bearing 3 is set, are respectively arranged in two bearing grooves 13,12 one end of through hole is
Insertion end 121, the other end are locking end 122, and the bearing 3 in bearing groove 13 at insertion end 121, internal diameter is greater than through hole
12 aperture, the bearing 3 in bearing groove 13 at locking end 122, internal diameter are less than the aperture of through hole 12；Rotary core 2 from
The insertion end 121 of through hole 12 is installed in installation position, and rotary core 2 realizes rotation connection by bearings at both ends 3 and oil path block 1,
Two bearings 3, through hole 12, rotary core 2 are coaxially arranged；Rotary core 2, which is equipped with, holds out against portion 21, axis with what 3 inner ring of bearing cooperated
The bearing groove 13 for holding 3 outer rings and oil path block is interference fitted, and the portion 21 that holds out against of 3 inner ring of bearing and rotary core 2 is interference fitted, oil path block
1 through hole 12 and 2 clearance fit of rotary core, the hole wall of through hole 12 are equipped with several oil seal grooves 123, peace in oil seal groove 123
Equipped with oil sealing 14, oil sealing 14 closes the oil circuit formed between oil path block 1 and rotary core 2；The preferred thin-walled deep groove ball bearing of bearing 3,
And bearing 3 is shield bearing.
The center current divider of this kind of spin stabilization, its working principles are as follows: two bearings 3 are respectively arranged in through hole 12
In two bearing grooves 13 at both ends, rotary core 2 is packed into through hole 12 from insertion end 121 up to two of rotary core 2 hold out against portion
21 connect with the inner ring of two bearings 3 respectively；Due to the bearing 3 at insertion end 121 in bearing groove 13, internal diameter is greater than through hole 12
